urlmatch: allow wildcard-based matches

Hi,

this is version 5 of my patch series. The previous version can be found at [1]. The use case is to be able to configure an HTTP proxy for all subdomains of a domain where there are hundreds of subdomains.

This includes only a single change, interdiff is included below. The previous version had an embarassing bug because a variable was not properly initialized in all cases, leading to undefined behavior. I also verified that the patches work on top of 4e59582ff (Seventh batch for 2.12, 2017-01-23), where Junio reported the test failures.

Regards
Patrick
